A/C Ev***rator was leaking pretty bad on this 2010 BMW 128i.
As you can see here, its not an easy job and very labor intensive.
Full dash, center console and HVAC box removed the back together.
This is fairly common problem on several different chassis. Takes about a week to complete this job.
❄️ Acting as the primary heat exchanger within the IHKA (automatic climate control) housing, the ev***rator drops cabin temperatures by utilizing low-pressure, low-temperature liquid refrigerant to absorb thermal energy from incoming air.
As ambient air passes over its aluminum fins, state-change physics convert the refrigerant into a low-pressure v***r. This process simultaneously pulls latent moisture from the air for cabin dehumidification and condensation management.
Engineered with a dedicated ev***rator temperature sensor, the vehicle’s DME/IHKA modules dynamically adjust compressor displacement to keep core temperatures strictly above 34 degrees preventing surface icing and maintaining optimal volumetric airflow.
